(Cl. 312100) ABSTRACT OF THE DISQLOSUREA housing for gasoline dispensing apparatus having an upper and a lowerclosure member on both the front and rear side. The upper closuremembers contain a glass panel and a dial face secured in position by amultiplicity of spring clips. Positioning pins are mounted on a supportframe in a manner whereby an upper and a lower closure member arealigned with and commonly secured to a pair of positioning pins.

Our invention relates to liquid dispensing apparatus, such as gasolinedispensing apparatus, and more particularly to what is commonly known asthe housing of such apparatus.

Heretofore, housing for such liquid dispensing apparatus ordinarilyincluded panels or doors at the front and back of the apparatus, or onlyat the front of the apparatus, which are hingedly connected, so thatsuch hinged panels or doors, may be opened, or removed, to permit accessto the components of the apparatus within the housing. Such hingedpanels or doors have been uniformly used for a long number of years, andall manufacturers of gasoline dispensing apparatus have had problems inassuring that the doors are properly aligned and positioned so that theywill open, or be removed, readily and can be maintained closed inweathertight condition.

All of such gasoline dispensing apparatus which are in common use inservice stations include an upper portion provided with a glass portionthrough which a dial face may be observed by the customer, the dial faceincluding a multiplicity of openings through which the computer numberedindicating dial wheels for the volume, total sales value, and price pergallon may be observed. Such glass enclosed portion may be formed as theupper part of the panel or door, or may be comprised of a separate panelor door element. Such glass portion, or door, including the glass, isformed as a sub-assembly, with retainin-g means around the peripheraledge of the glass, which retaining means is secured by a multiplicity ofscrews which require a relatively considerable amount of time toassemble, and also to disassemble in the event the glass becomes brokenand has to be removed, and a new glass installed, and then reassembled.

Summary of the invention Our invention is to provide a housingconstruction in which a bottom flange formed in the lower door closuremay be readily positioned on pin positioning means which are adapted toextend through coinciding openings formed in said flange of the lowerdoor closure. The upper portion of the lower door closure also isprovided with a horizontal flange having similar openings therethroughwhich are adapted to be positioned over spaced apart positioning pinsrigidly connected to a cross member of the frame of the unit. The upperdoor closure includes an outer frame and the glass member through whichthe dial may be observed. Said upper door closure includes spaced apartopenings through a bottom flange of said door, which openings coincidewith the spaced apart upper pin members which extend through the upperflange of the lower door member. The uppermost portion of the upper dooris adapted to engage a trough-like cross member rigidly connected to thefixed portion of the top of the housing.

An object of our invention is to provide means by which said upper andlower doors or panelsmay be facilely locked together by a single lockingmember to prevent any unauthorized access to the interior of thehousing.

Another object of our invention is: to provide means by which the glassportion of the upper panel or door may be readily secured to the doorframe by means of quick acting spring clips which are readily snappedinto locked position, and, accordingly, which may be readily and quicklyremoved to permit the removal of the glass.

Our invention may be more fully understood and further objects andadvantages may become apparent when reference is made to the moredetailed description of the invention with respect to the accompanyingdrawings.

FIG. 6 is an enlarged elevation of the lock member indicated in FIG. 1,with said lock member when turned to unlocked position shown in dash anddot lines.

FIG. 7 is an exploded perspective view of the liquid dispensingapparatus shown in FIG. 1, with the upper and lower door closures, andelements of the lock member, shown separated from the apparatus.

FIG. 8 is an enlarged fragmentary sectional view of the lock member inlocked position, so that the lower and upper doors may not be raised offthe positioning pins, and showing the manner in which the lower andupper doors are locked in position on the positioning pins.

Referring more particularly to FIGS. 1, 2, and 3; the outer housingindicated generally at 1 includes a lower front door closure 2 and anupper door closure 3. The rear of the pump is provided withcorresponding upper and lower door closures. The housing includes arighthand side panel member 4 which is provided at its upper portionwith an outlet connection 5 to which a commonly used dispensing hose(not shown) is connected in fluid tight relationship. The hose isprovided at its distal end with a valve controlled dispensing nozzle(not shown) of the ordinarily well-known construction.

The side panel 4 is provided with a nozzle boot 6 into which said nozzlemay be positioned with the lower end of the nozzle handle positioned onthe nozzle support 7. The handle of the switch operating means for theusual electric motor is indicated at 8. The opposite side panel on theleft-hand side of the pum as in FIG. 1, is similar to the panel 4,except that it does not include a nozzle support, nozzle boot, switchoperating handle, etc. The top of the housing is provided with a topclosure portion 9.

The liquid dispensing apparatus includes support frame members withinthe housing, said support frame including vertical members 10, 11, etc.and horizontal bracing members such as indicated at 12, 13, etc. Thesupport frame is rigidly mounted on a base support member 15.

The base member has an inwardly turned horizontal flange portion 16which is provided with a multiplicity of positioning pin members 18which extend through openings formed in the flange 16 of the base member15 and are rigidly connected to said flange 16. The rear side of thebase member 15 has a corresponding flange 16, pins 18, etc.

The bottom of the lower door 2 is provided with an inwardly turnedflange portion 20 provided with spaced apart openings 21 coinciding withthe spaced apart positioning pin members 18. Each of the openings 21 isprovided with a grommet 22 formed of resilient material and providedwith a peripheral slot portion through which the metal of the bottomflange surrounding the opening 21 is engaged to retain the grommet inposition. The grommet, of course, is provided with a central openingtherethrough of a diameter which will fit snugly around its pin 18.

The supporting frame includes a horizontal rigidly fixed frame member 25which has rigidly connected thereto spaced apart positioning pins 26.

The top of the lower door closure 2 is provided with an inwardly turnedflange which is provided with openings 31 therethrough which are inspaced apart matching relationship with the spaced apart positioningpins 26.

The lower edge of the upper door closure 3 has an inwardly turnedhorizontal flange portion 32 which is provided with openings 34therethrough in matching spaced apart relationship with the spaced apartpins 26 rigidly positioned in the horizontal frame member 25. As bestshown in FIG. 3, the top portion 9 of the housing includes a formedU-shaped channel member 36 which is adapted to receive the downwardlyand inwardly turned upper edge 37 of the upper door member 3.

It is to be particularly noted that the positioning pin members 18rigidly connected to the flange 16 of the base member 15, are of greaterlength than the positioning pins 26 rigidly connected to the framemember 25, so that the lower door closure 2 may be first positioned onthe longer pins 18 and then the door raised so that the pins 26 may bepositioned through the openings 31 in the inwardly turned flange 30 atthe top of the door member 2.

Referring more particularly to FIGS. 7 and 8; the upper portion of thelower door 2 is provided with an opening 40, with flattened sides 41,through which the barrel 42 of the lock member indicated generally at 43is inserted. The barrel portion 42 of the lock member 43 is providedwith flattened sides of a congruent configuration similar to that of theopening 40, so as to prevent turning movement of the lock barrel 42 inthe opening 40. After the barrel 42 of the lock member 43 is insertedthrough the opening 40, the latch member 45 provided with opening of acon-figuration congruent to the inner end of the barrel 42 is positionedon the inner end 46 of the barrel 42, and conveniently rigidly aflixedthereto by means of the nut 47. The latch member 45 is provided with acam-like surface 50, as best shown in FIG. 8.

The inwardly turned flange portions '30 and 32 of the lower door member2 and the upper door member 3 are provided, respectively, with matchingopenings 51 and 52, and the horizontal frame member 25 is provided witha notched out portion 53, so that when the lock 43 and its rigidlyaflixed locking member 45 are turned counterclockwise from the positionshown in dash and dotted lines in FIG. 8 to the position shown in fulllines in FIG. 8, the cam surface 50 of the locking member 45 causes thecam 50 to wedge against the frame cross member 25, thereby forcing thelower door 2 downwardly. The lock member 45 also hooks over the opening52 of the flange portion 32 of the upper door 3, thereby preventing theupper door 3 from being raised off its positioning pins 26, to therebylock both the lower and upper doors in position on the pin members 18and 26.

Referring more particularly to FIGS. 3 and 4; the upper door member 3includes an outer frame portion provided with a rectangular peripheralflange 56 forming an enlarged opening 57 in the upper door member 3. Arectangular glass 58 is provided with protective resilient means 60around its periphery, the resilient means 60 resting tightly against theflange portion 56 of the upper door 3, as best shown in FIG. 3. A dialmember 62 of a configuration substantially congruent with that of theresilient protective means 60, is positioned against the inner side ofthe resilient protective means 60. The dial member 62 is provided with aseries of openings 65 through which the figures on the dial wheels 66 ofthe computer 67 will appear. The computer 67 is operatively connected tothe output drive shaft of the meter 68 in the well-known manner.

The glass 58, with its peripheral resilient protective means 60, and thedial member 62 are secured in tight engaging contact with the flange 56of the upper door member 3 by means of a multiplicity of spring clips70, one end of each of said clips 70 bears against the perimeter of thedial 62, and the inner end of each clip being outwardly turned to bearagainst the inwardly turned portion 37 of the upper door member 3.

Assembly and disassembly of the lower door closure 2 and the upper doorclosure 3 The lower front (or rear) door closure 2 is fitted over thepositioning pins 18. The pins 18 being of greater length than the pins26, the pins 18 act as a pilot for the lower flange 20 of the lower door2, while the upper flange 31) of the lower door 2 is being positionedover the pins 26. The openings 34 in the lower flange 32 of the upperdoor 3 are positioned over the pins 26 and the upper inwardly turnedflange portion 37 of the door 3 is hooked into the U-channel member 36of the top portion of the housing.

With the lower door 2 and upper door 3 positioned in place on thepositioning pins 18 and 26, a key (not shown) is inserted in the lock 43and the key, barrel 42, and latch member 45 are turned counterclockwiseapproximately Such 90 counterclockwise movement of the latch member 45causes the cam surface 50 of the lock member 45 to wedge against theframe rail 25, forcing the lower door 2 downwardly. The latch member 45also hooks over the lower flange 32 of the upper door 3, as best shownin FIG. 8, so that the upper door 3 is prevented from being raised offthe positioning pins 26, thereby locking both the lower door 2 and theupper door 3 in position on the pins 18 and 26.

When it is desired to have access to the mechanism within the interiorof the housing, the lock 43 is turned 90 clockwise to the position shownin dotted lines in FIG. 8, to thereby permit the upper door 3 to belifted out of the U-channel member 36 and otf the positioning pins 26.With the upper door removed from the positioning pins 26, the lower door2 may be moved upwardly from engaging contact with the positioning pins26 and then tilted slightly forwardly to permit removal of the lowerdoor 2 from the positioning pins 18 rigidly secured in the flange 16 ofthe base member 15.

If the glass 58 of the upper door needs to be replaced for any reason,the upper door 3 is removed as heretofore described and the spring clips70 may be quickly removed thereby permitting removal of the dial 62 andthe glass 58. A new glass replacement is then inserted, the dial againplaced in contact as heretofore described, and the multiplicity ofspring clips 70 quickly snapped into tight holding position.

We do not desire to limit ourselves to the precise details ofconstruction and arrangement heretofore described, as it is obvious thatvarious modifications in our invention may be made without departingfrom the essential features thereof as defined in the appended claims.
